About Metres per kilogram
The metre per kilogram (m/kg) is the SI coherent derived unit of mass-based fuel efficiency. It is used in combustion research, rocket propellant comparative testing, and laboratory fuel-cell efficiency benchmarking. A car at 15 km/kg petrol = 15 000 m/kg; a hydrogen fuel cell bus at 120 km/kg H₂ = 120 000 m/kg. 1 m/kg = 1e⁻³ km/kg = 1/1000 km/kg.
About Feet per pound
The foot per pound (ft/lb) equals ≈6.720 × 10⁻⁴ km/kg, the smallest practical mass-efficiency unit. It appears in historical US Army ballistic tables and early solid-propellant rocket motor test sheets where range was in feet and propellant charge in pounds. 1 ft/lb ≈6.720 × 10⁻⁴ km/kg ≈1/3 the size of a metre per pound.
